• The wear properties of Bis・GMA-Tri・EDMA based composite resins to an Ag Pd-Cu-Au alloy examined, using a trial sliding frictional wear testing machine, and the effects of water in a specimen on wearing claaracteristics were discussed. The water absorbed into the specimens softened the surface of the material and decreased the wear-resistant properties of them. On the other hand, the increase of Bis ・GMA content improved slightly the wear characteristics. In the range of 60-76 wt% filler content, the wear of experimental composite resin decreased according to increase of filler content. In the case of 50 wt% filler contentresins, however, the wear of experimental composite resins was significantly less than in the other cases. There was high negative correlation between wear rate and Vicker's hardness of experimental composite resins (r= -0.84). In addition, there was high correlation between wear rate and amout of absorbed water in the specimens of 76 wt% filter (r=0.92).
